* Step 4: Filter out the zuora subscription in the test based on the md5 has of the `ultimate_parent_sub` name

* Step 5: Once finance has confirmed that the accounts and subscriptions have been updated, create a MR to remove the filter

### Test: zuora_assert_no_circular_linkages

This custom test asserts `zuora_subscription_intermediate` has no circular linkage. A circular linkage is created when the `zuora_renewal_subscription_name_slugify` is equal to the `subscription_name_slugify` in the `zuora_subscription_intermediate`.

When the test fails, the `zuora_subscription_lineage` model will fail with the following error:

* Step 2: Create an issue in finance asking for the Zuora subscription lineage to be reviewed.

* Step 3: Create an issue to remove the filter and assign it to the next milestone, cross-link it to the original issue

* Step 4: Filter out the zuora account in the base `zuora_subscription` model and submit your MR for review

* We filter from the base model instead of the test because downstream models (such as retention) will fail otherwise

* Step 5: Once finance has confirmed that the account has been updated, create a MR to remove the filter

### Test: uncategorized_pings

This test checks that the list of unique ping metrics that we receive, `pings_list`, matches the ping metrics that we have categorized in the static CSV, `ping_metrics_to_stage_mapping_data`. This test will fail when these two sources get out of sync in either direction.
